Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00655 |
| Opus 5 | $0.00026 | $0.00328 |
| Sonnet 5 | $0.00011 | $0.00131 |
| Haiku 4.5 | $0.00005 | $0.00065 |
Grade A, and why
askit-init-marketplace scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 33 lines — stays where its author put it; the contents beside it link to each section on GitHub.
askit-init-marketplace
Purpose
Scaffold and validate a distribution index that catalogs plugins, in each target's native format. create scaffolds the marketplace index per target; validate checks that every entry resolves to a real plugin and that versions are consistent. The two native formats and the entry shape are in references/marketplace-format.md.
When to use
When standing up a marketplace, adding a plugin to one, or validating marketplace entries.
create mode
- Read the target agents and the plugin roster to catalog.
- Scaffold the index per target: Claude Code
.claude-plugin/marketplace.json; Codex.agents/plugins/marketplace.json(Standard sec 12). Each entry names the plugin, its source or path, and its version. - Pick the source kind that matches how the plugin is actually distributed: a bare path,
url/github(with ashato pin it),npm,archive(which requires asha256), orgit-subdir. The full table is in the reference. - If an entry has shipped under a previous name, record it in
renamesso consumers following the old name can be redirected. - Keep the catalog separate from any single plugin's manifest (a marketplace catalogs plugins; it is not itself a plugin).
validate mode
- Each entry resolves to a real plugin (its source/path exists and carries a
library.json). - Versions are consistent (an entry's version matches the plugin's
library.jsonversion; no dangling or duplicate entries). - No
renamesvalue collides with a live entry name or with another entry'srenames. - For a whole-catalogue grade, run
node scripts/evaluate.mjs <catalogue-root>(marketplace scope). It grades every locally-resolvable member at its own declared tier and its own Standard pin, and reports the cross-member defects no per-plugin run can see: colliding skill and command names, a catalogue entry that resolves to nothing, and a registry version disagreeing with the member's own manifest.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

askit-init-marketplace is a skill published in the GitHub repository product-on-purpose/agent-skills-toolkit (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 53 tokens to every session and 655 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

modelchk
Size a task's run before spending it: the cheapest sufficient capability tier (fast, standard, frontier) and the reasoning effort within it, on a neutral scale that binds to whatever levels the model exposes. Use when work seems over- or under-powered, costly, ambiguous, or high-risk, or asks which model class and how…
autobahn
Carve guardrail-adjacent items out of scope with safe alternatives before risk-adjacent work starts, then run the safe remainder at full strength in a fresh subagent that only ever sees the carved prompt, never the risky input. Use when a task includes stealth, scraping, privacy, IP, policy, licensing, security, or…
re0-release
Walk a pending change through this repo's shipping and releasing checklist end to end, then tag and publish once confirmed. User-invoked: run it when you've decided to ship.
ssotize
Audit and consolidate a fact that's scattered across places into one canonical source, after approval, and replace the rest with references. Use when asked to find duplication, check consistency, locate the source of truth, deduplicate, consolidate, unify, or establish SSOT across artifacts or platforms. Starts…
re0-plan
Open a paperthin iteration's casebook before re0-loop's first turn — seeded with real content the moment the folder exists, never an empty directory. User-invoked, paperthin-only: assumes the full skill package installed. Run when opening a new build cycle in this repo.
dedash
Remove em-dashes and the dashes standing in for them from a user-owned scope, reading each occurrence in context and choosing the punctuation or wording that fits.
